摘要
本文用北半球500百帕大气月均高度场资料,与云南地区每年发生的最大地震的震级作相关分析,选出其中影响地震的主要环流因子,分别构成每年上半年和下半年的最大震级预报方程。经三年的预报试验,效果尚好。
Based on the statistical correlation analysis,we find that the monthly mean geopotential height at 500 hPa which can be presented the circulation features over Northern Hemisphere is certain related to maximum earthquakes for Jan.-June and July-Dec. in Yunnan Province. From the stepwise regres-sion forecasting analysis mentioned above,it chooses main circulation factors influencing the earth-quakes,and sets up some regression forecasting equations for the maximum magnitude.
